It is pure instinct, when someone is trying to smash you into the ground, naturally you will grab at anything available.
I don't know if it is a few unhappy Daddy fans giving it more attention than it really merits. It makes little difference, Kenny will always beat Joe, he is a very well rounded fighter. Once BJ is done getting mauled by Georges, and back where he belongs defending his own belt, the fight with Kenny will be fantastic. You can do it Kenny!
